Claims. .(Ci. Z4874) This invention relates to new and usefulimprovements in pipe hangers for use particularly although notnecessarily, on ships and has for its primary object to provide, in amanner as hereinafterset forth, a pipe hanger which is adapted to beeirpeditiously installed beneath an insulated deck with aminimum ordamage to the insulation.

Anoher very important'object of the present invention is to provide, ina hanger of the aforementioned character comprising a saddle forreceiving the pipe, novel means for quickly, firmly but removablysecuring the pipe in said saddle.

Still another important object of the invention is to provide animproved pipe hanger of the character set forth which is readilyvertically adjustable relative to the deck or other overhead supportingstructure.

Another object of the invention is to provide an im- 7 proved hanger ofthe character described which is adapted to accommodate various sizes ofpipe within a given range. V

Other objects of the invention are to provide an improved pipe hangerwhich is comparatively simple in construction, strong, durable, compact,of light weight and which may be manufactured and installed at low cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which: 7 FIGURE 1is a perspective view of a pipe hanger constructed in accordance withthepresent invention, showingthe device installed; i

FIGURE 2 is a" view vertical section through the rear portion of thedevice, showing same installed;

FIGURE 3 is a sectional view on an enlarged scale through the connectedend portions of the pipe securing strap or band, taken substantially onthe line 33 of FIGURE 1;

FIGURE 4 is a vertical sectional View on an enlarged scale, takensubstantially on the line 4-4 of FIGURE 2;

FIGURE 5 is a perspective View of the hanger per se without thesuspension stud or rod;

FIGURE 6 is a view in side elevation of another embodiment of thehanger, showing same installed;

FIGURE 7 is a bottom plan view of the embodiment of FIGURE 6;

FIGURE 8 is a view in transverse section, taken substantially on theline 8 -8 of FIGURE 6; and

FIGURE 9 is a perspective viewof the clamp which is used on bothembodiments of the hanger.

Referring now to the drawing in'detail, it will be seen that theembodiment of the present invention which has *been illustratedinFIGURESI to-S, inclusive, of said drawing comprises a threadedsuspension rod, shank orstud 9 of suitable inetal. Thesuspension stud 9may also be of any desired length and diameter. The stud 9extendsflupwardly through an opening 1% provided there for in theinsulation 11 beneath the steel ship deck 12 and has its upper endportion riveted or otherwise anchor ed in said deck, as indicated at 13.In the installation shown, the steel deck 12 is apertured as indicatedat 14 to accommodate the stud 9.

' Removably and adjustably mounted on the lower end portion of thesuspension stud 9 is a generally U-shaped The generally ICC whichterminates in a right angular 1y bent, horizjon'tel free end portion orflange '17 which is aperturie d; to acf co'mmodate the stud 9.Threadedly mounted on. the" 9 is a plate-likenut 18 beneath which theflange 17 of the saddle 15 is e'ngaged. A nut 19 is threaded on the stud9 beneath the flange 1 7. ,rhe nuts 215E119 ad justably secure theflange 17 on the stud 9 in an obvious manner. 7 i A,

The saddle 15 is for the reception of the pipe to hung, as indicated at20. A longitudinally split, tubular pad or sleeve 21 is provided on theportion of the pipe 20 which rests in thesaddle 15. clamp 22 secures theThe clamp 22 comprises a flat metallic band; or v H p 23 which isthreaded through a trarisverse slot 24 pi-of vided therefor in the upperportion ofthe back leg 16 of the saddle 15. One portion of the strap 23passes beneath the saddle 15 and the other end pbrtionofsaid' strappasses over the pipe 20. The end portions; of the v strap 23 areadjustablyand detach'ably connected through the medium of a metallicconnector or clip 2h. The clip or connector 25 includes; in theembodiment shown, a rectangular metallic plate 26 having formedintegrally with one end portion thereof a transverse. loop Formedintegrally with the other end portion of the plate 26, on thelongitudinal sides thereof,1 are bendable cars 28'. One end portion ofthe strap 25 inserted through the loop 27 and is downwardlyand reverselybeht in a manner to provide a hook or, the like 29 ifr wllich plate 25is engaged. The other end portion of; the strap 23 is inserted betweenthe outstanding ears 28 over the other end portion of said strap,inserted through the loop 27 and outwardly and reversely bent in a mahrertc} pr givide a hook 30 in whichthe loop 27,, is engaged and whichextends between the'ears 281 The ears 28 are ther l clinched on thereversely bent end portion' or hook 30 and the connection iscorhplete,)1 4 a u i It is thought that the use of t he hanger will readilyapparent from a consideration of foregoing Of course, to install thedevice the threaded suspension rod; shank or stud 9 is mounted on thedeck structure or other overhead support beneath which the pipe is to bemounted. The saddle 15 is then slipped on the stud 9, adjusted to thedesired position and secured between the threaded elements 18 and 19. Itwill be noted that the construction is such as to permit rotary as wellas vertical adjustment. With the protective pad or sleeve 21 thereon,the pipe 20 is then engaged in the saddle 51 and firmly secured throughthe medium of the clamp 22. It also will be noted that the constructionis such as to accommodate various-sizes of pipe. An opening 31 in theflange v studs 32 which are suspended from the insulated deck structureor other overhead support 12. Adjustably and removably mountedbetween'the lower end portions of the studsSZ is a'substantiallyinverted U-shaped saddle 33 of suitable metal. The saddle 33'is providedon its ends with integral, outwardly projecting horizontal ears orflanges 34 through which the lower end portions of the studs 32 pass.The portions 34 of the" saddle 33 are secured in adjusted position onthestudsSZ between pairs of nuts 35 threaded on said studs. V v

The saddle 33 is for the reception of the pipe to be hung, as indicatedat 36. The portion of the pipe 36 which isengaged in the saddle 33 isprovided with a pro- 2 U gated openings or slots 38. The openings orslots 38 are for the passage of the straps 23 of a pair of the clamps 22which secure the pipe 36 in the saddle 33. This is shown to advantage inFIGURE 7 of the drawing. It will be observed that the straps arethreaded in opposite directions through the openings 38 while the clipsor connectors 25 are located beneath opposite side portions of the pipe.

In use, the studs 32 are suspended from the deck structure 12 and thesaddle 33 is mounted between said studs.

The pipe 36 is then engaged beneath the saddle 33 and the clamps 22 areapplied. The saddle 33 is adjustable vertically on the studs 32 byreason of the nuts 35. This vertical adjustment may be made eitherbefore or after the pipe is secured in the saddle. This also applies tothe embodiment of FIGURE 1 of the drawing.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
